Product Description
From Amazon
Among network designers and administrators, wired Ethernet is a known quantity. Plenty is known about how to build good twisted-pair network infrastructures, how to keep them secure, and how to monitor their excess capacity. Not so for the wireless Ethernet networks (built around the IEEE 802.11x standards)--these hold much more mystery for even experienced network designers. 802.11 Wireless Networks: The Definitive Guide aims to codify the body of knowledge needed to design and maintain wireless local area networks (LANs). The authors succeed admirably in this, covering what installation and administration teams need to know and digging into information of use to driver writers and others working at lower levels.
The only significant detail that's been excluded has to do with security--a notorious weak point of 802.11x LANs. The authors cover the feeble but widely used Wired Equivalent Privacy (WEP) authentication protocol in detail and devote another whole chapter to 802.1x, which is an emerging authentication scheme based on Extensible Authentication Protocol (EAP). The author has considerable skill in communicating information graphically and does a great job of using graphs to show how communications frequencies shift over time and how conversations among access points and network nodes progress over time. This is indeed an authoritative document. --David Wall
Topics covered: How IEEE 802.11a and 802.11b wireless networks (also known as WiFi networks) work, and how to configure your own. The framing specification is covered well, as are authentication protocols and (in detail) the physical phenomena that affect IEEE 802.11x radio transmissions. There's advice on how to design a wireless network topology, and how to go about network traffic analysis and performance improvement.
Review
'Building Wireless Community Networks is an enthusiastic introductory guide to a technology which can really be put to use to change people's lives. Wireless gives the power of the network back to the people, and this book helps to demystify the technology and enable any community to take control.' Linux User, March/April (Classic Title)

An Excellent Choice,
By Michael Pucciarelli (Rockville, MD United States) - See all my reviews
This review is from: 802.11 Wireless Networks: The Definitive Guide: Creating and Administering Wireless Networks (Paperback)
I really liked this book. It helped me write my research paper for UMUC MSIT 640 - Data Communications and Networks. The book has a lot of useful information. It has a good section on the different types of antennas. The book has a lot of Acronymns that are clearly explained. Generally, I think all oreilly books are very good. The book talks a lot about the wireless LAN. It includes many disadantages and advantages. The book also has a lot of useful diagrams. I would recommend this book to anyone who wants to learn about the wireless LAN.

The best reference in this field till now,
By scott lynn (Chengdu, P.R China) - See all my reviews
This review is from: 802.11 Wireless Networks: The Definitive Guide: Creating and Administering Wireless Networks (Paperback)
It is organized well according to the IEEE 802.11 version of 1999. The concept of WLAN is clarified clearly.But the content of 802.11a seems lacking for a better understanding. Several chapters introducing the products from vendors are useless to me. I hope the next edition will give more description on 802.11a, 11e and 11g.

This review is from: 802.11 Wireless Networks: The Definitive Guide: Creating and Administering Wireless Networks (Paperback)
Recently I've been designing a system to run atop 802.11b radios and this book has served as an excellent introduction to the 802.11b standard. For example, Gast's description of spread-spectrum radios, chipping, and OFDMA radio systems is a broad overview without going into excessive mathematical formulas and it gives a non-RF engineer a basic understanding of what are the issues underlying each of the 802.11 radios of today.I found myself reading a chapter of this book, and then looking at the 802.11b standard itself (now available free on the website ieee.org) for more detailed information. I found only a couple of minor errors in this book. This book serves as an outstanding introduction to the protocol standard, which is large and which contains little or no practical information for the practitioner. However, I did also use Radia Perlman's book on Routing in conjunction with this book to help me understand IEEE 802.1 issues. Gast attempts to be a be-all and end-all book for everyone. For example, he attempts to describe all 802.11 RF modulation schemes. He attempts to give a full description of all the packet formats. He attempts to describe which cards are based on which baseband (Intersil or Orinoco). This stuff is changing very fast but he gave it his best shot, and its very important to people installing *NIX drivers. He attempts to tell you how to set up an 802.11 Ethereal packet sniffer. All of his information is invaluable to anyone setting up 802.11b on any flavor of UNIX or Linux. Anyway, he makes a really valiant effort and I've never seen a networking book try to play in all 4 spaces at once - RF Theory, Network Protocols, Hardware Selection, and Practicum - all at the same time. He should be applauded for this attempt. I have not found a book that is nearly as comprehensive (6/2003) and I've lent this book to at least 5 other people, most of them PhD's or VP's in EE or CS and/or wireless communications.
